Further tests are being carried out to find the cause of death of a company director whose firm supplied Tasers used during the stand-off with gunman Raoul Moat.
An inquest opening into the death of Peter Boatman, 57, director of operations for Pro-Tect Systems, heard that post-mortem examinations are awaiting toxicology and histology tests.
No members of Mr Boatman's family were present during the short hearing at Northampton General Hospital. The coroner adjourned the inquest to a date to be fixed.
Mr Boatman was found dead at his home in Reynard Way, Kingsthorpe, Northampton, on Friday, just three days after the Home Office revoked Pro-Tect Systems' licence to import and sell Tasers.
The move came after it emerged that the firm breached the terms of its licence by supplying X12 Tasers, which were still being tested by Government scientists, directly to police involved in the Moat manhunt.
On Friday, Mr Boatman's business partner said the former police officer was "destroyed" by the furore.
Pro-Tect's managing director Kevin Coles said there was "no doubt" his colleague's apparent suicide was linked to the week's events.
He said: "He was a proud man and he felt ashamed at recent developments.
"He spent all his life involved in officer safety and what happened was a result of him being worried about the welfare of officers. He knew there was something there that would offer the officers protection and that was what his motive was.
"The furore over it destroyed him."
